Has this been a common issue with the FA20 engine? Is there a known camshaft journal oiling issue that needs to be addressed?

I'm replacing all four camshafts, and both cam carriers, but want to be sure I do what I can to make this set live a bit happier life.

The four oil strainers/filters that the front journals get fed oil from were very clean, so I'm assuming the oil going to the rear journals was also clean.

I decided to use a blow gun to confirm flow to all the feed passages to the journals, but it's proving to be a bit hard to confirm that there is adaquate flow.



I removed the threaded plugs at the end of each galley and used a borescope to have a look down the length of the galleys. I was expecting a clear path from the rear of the cylinder head, all the way thru to the ball bearing plug at the front of each galley, but found what appears to be a restrictor with a very small orfice drilled in it. I guess they are trying to limit oil flow to the rear of the cylinder heads (rocker pivots, center and rear cam journals)

Anyhow, I thought I'd inquire as to whether this cam wear has been seen by others at this kind of mileage, and if there is any remedies to lessen the wear issue.

FWIW: I don't know how far along you are with this project but most folks are going with a FA24 swap rather than mess with rebuilding a FA20.
